VALVE LIFTER.

Application filed February 1, 1922. Serial No. 533,432.

. and useful Valve Lifter, of which the following is a specification.

This invention relates to valve spring compressors, the primary objectof the invention being to provide a valve spring compressor for use inconnection with valve springs of various lengths.

Another object of the invention is to provide means to facilitate theapplication of the lifter under the washer supported at the base of avalve spring.

A still further object of the invention is the provision of means forlocking the valve spring compressor in its positions of adjustment,permitting the operator to have unrestricted use of his hands toaccomplish the removal of the valve.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing Figure 1 is an elevational view of a valvespring compressor constructed in accordance with the present invention.

Figure 2 is an elevational view of the same.

Figure 3 is a sectional view taken on line 3 3 of Figure 2.

Figure 4 is an elevational view of the lower jaw of the springcompressor.

Referring to the drawing in detail, the device embodies a lower arm 5and an upper arm 6, each arm being formed with an extension 7 throughwhich the arms may be pivotally connected.

Formed at the outer end of the arm 5 is a jaw 8, which is constructed toengage a shoulder 9 formed at the base of the valve spring opening of anengine valve, as clearly shown by Figure 1 of the drawing.

The jaw 8 is bifurcated sol that the same may be slid into positionaround a valve stem, which in the present showing is indica-ted at 10,the valve stem being provided with asuitable opening to accommodate thepin 11 employed for supporting the lower extremity of a valve spring.

The upper arm 6 has a curved extremity 12 forming one section of theupper jaw, the opposite section of the jaw beingindicated at 13 andpivotally connected. to the arm 111 carried by the jaw 12. This arm 14Cextends laterally from the yjaw 12 and is formed 1 with a plurality ofopenings 15 disposed in spaced relation with each other, to accommodatethe pin 16 which passes through an opening in the jaw section 13,permitting the jaw 13 to be adjusted with respect to the stationarysection 12 of the jaw.

As clearly shown by Figure 3 of the drawing, each of the sec-tions 12and 13 is curved transversely of its width to fit around a valve head,so that when the jaw sections are positioned over a valve, the jawsections will be held thereon, and restricted from movement. Arearwardly extending arm 17 forms a part of the jaw section 13 and` isformed with a relatively flat portion 18 to.

be engaged by the hand of the operator when it is desired to open thejaw sections to apply the tool. A coiled spring indicated at 19 isdisposed between the arms 6 and' rearwardly extending portions 17 of thejaw section 18, for normally urging the jaw sections towards each otherin gripping relation with each other.

Carried at the inner end of the arm 5 is a pivoted rod 20 formed with athreaded portion 21 to receive the winged nut 22. The arm 6 is formedwith a notched portion 23 disposed in one end thereof, which notchedportion is designed to accommodate the rod 20, providing means to securethe arms 5 and 6 against movement, when the same have been applied to avalve. In order that the rod 20 will be restricted from moving out ofthe notched portion of the arm 6,

the extreme'inner end of the arm is extended upwardly as at 23,providing stops or abutments to be engaged by the winged er to relievethe pin 1l of the tension of the spring.

It follows that the rod 20 is now moved to lool; the arms 5 and 6against movement.

Having thus described the invention what is claimed as new is l. ln aValve spring compressor, opposed arms pivotally connected, one of saidarms having a bifurcated extermity to be positioned over a Valve stem,lone end of the opposed arm being curved, a jaw section cooperatingwitli the curved end to grip a valven washer, said jaw section havingpivotal connection with the curved end and having a rearwardly extendedarm adapted to lie in spaced relation with the secondmentioned arm topermit the pivoted jaw section to move with respect to the curved end ofthe second mentioned arm, and resilient means for normally urging thejaw section to its active position.

2. In a Valve lifter, an upper arm and a lower arm pivotally connected,the lower arm 'having a bifurcated end to lit around a valve stem, theupper arm having a curved end forming a jaw, al laterally extendingmember formed on the upper arm and having spaced openings, a pivoted jawsection cooperating with the jaw of the upper arm, means for pivotallyconnecting the j aw section to the laterally extending member, saidpivoted aw section lhaving a rearwardly and outwardly extended portionlying in spaced relationv with the upper arm, and means for normallyurging the jaw section towards the j aw of the upper arm.

ln testimony that I claim the foregoing as my own, I have hereto afixedmy signature in the presence of two witnesses.
